     - **Full project history**: Metric charts on project panels include data from _all runs_ in the project, not only the latest run.
     - **Star projects**: See your most important projects at a glance. Click the star icon next to a project to star it. To filter the list to only starred projects, click the **Starred** tab at the top of the list.
 - **Track experiments**: View run status, metrics, and line plots for your experiments in real time.
+    - **Live updates**: Charts refresh as new data arrives. The **Runs** tab and project run lists update automatically when new runs start.
     - **Run overview tab**: On each run, open the **Overview** tab for a dedicated summary of run details alongside metrics and logs. Long run config values wrap to multiple lines instead of truncating.
     - **View system metrics**: On each run, open the **Metrics** tab to view [system metrics](/models/ref/python/experiments/system-metrics) that W&B logs automatically during training, such as GPU utilization, CPU usage, memory, disk I/O, and network traffic. System metrics appear in a collapsible **System** section alongside your logged metrics. Each metric displays as a line chart with the same tooltip and search behavior as other metrics on the tab.
-    - **Mobile-optimized panel grouping**: The app automatically groups panels by name into collapsible sections. Sections are a single level (not nested), and grouping follows the same rules as [workspace panels](/models/app/features/panels) in the W&B web app, so the layout stays consistent when you move between desktop and your phone.
+    - **Mobile-optimized panel grouping**: Panels are automatically grouped by name into collapsible sections. You can collapse the ungrouped metrics section to focus on named sections. Sections are a single level (not nested), and grouping follows the same rules as [workspace panels](/models/app/features/panels) in the W&B web app, so the layout stays consistent when you move between desktop and your phone.
     - **Star panels**: See your most important panels at a glance. When viewing a run or a project, click the star icon at the top of a panel to star it. To filter the list to only starred panels, click the **Starred** tab at the top of the list.
     - **Search panels**: When viewing a run or a project, use the **panel search** field at the bottom of the screen to filter which runs appear in each chart. You can search with [JavaScript regular expressions](https://www.w3schools.com/js/js_regexp.asp) to match patterns in run names.
     - **Chart tooltips**: On line charts, tooltips show metric values with up to four decimal places so you can read small changes accurately.
